' SAFETY DEVICE FOR WRINGERS.

' Application filed July 14, 1921. Serial No. 484,681.

F. SNYDER,

my invention are to provide in clothes,

wringers a safety device to eliminate the danger of the operator gettinghis fingers caught between the rolls further the provision of a manuallyoperated attachment for wringer rolls in the form of a fabric guidehaving, preferably, a' pivotal connection with the wringer frame so thatthe guide can be manually shifted from and toward the bite of the. rollsand instantly withdrawn in case of over-feeding, in which the guide isadapted in inward position to projectinto the space between theperipheries of the rolls opposite the bite thereof and preferablysubstantially into contact with a roll, and no closer, whereby to causethe fabric to be grabbed by the rolls with,

out drawing the guide along with it; further the provision of such adevice which is constructed and arranged to be quickly attached toeither side of the 'wringer rolls; further in the provision of-fabricguiding means adapted to automatically return to its normal positionremoved from the rolls after the fabrics have passed therefrom to thewringer so as to be in position to receive a new batch; further in theprovision of a guiding means adapted to beheld in operative positionadjacent the bite of the rolls due to the dragging of the fabricspassing over the guiding means'as they are passing through the rolls,further in providing fabric guiding or supporting means constructed andarranged to be positioned adjacent the bite between the rolls to feedthe fabrics theretoand to be shifted to a position removed'therefrom toreceive a fresh supply of fabrics, said guiding means being adapted tosubstantially shield the bite of the rolls when infabric receivingwrapped around the rolls; further to prevent. buttons from tearing offor becoming broken While the article carrying the same is being'fedthrough the wringer; further to provide a safety device-of improvedconstruction, and one that can be readily transferred from one side ofthe machine to the other; further to produce a safety device of maximumsimplicity, efficiency, economy and ease of operation, and such furtherobjects, advanta es and capabilities as will later more fuldy appear.

My invention further resides in the combination, construction andarrangement of parts illustrated in the accompanying drawings, and whileI have shown therein a preferred embodiment I desire it to be understoodthat the same is susceptible of modification and change, withoutdeparting from the spirit of my invention.

In the drawings Fig. 1 is a side elevation of a wringer having myimproved safety device attached thereto.

Fig. 2 is a vertical transverse section on a line 2-2 of Fig. 1. v

Fig. 3 is a perspective view looking toward the under side of the safetydevice.

Referring to the drawings, my improved safety device isdesignatedgenerally at A, and comprises the clothes support or guiding means 1,which at its upper forward side when in the position shown in Figs. 1and 2, is preferably fiat, as shown at 2, which fiat portion merges intothe downwardly and outwardly curved face 3, terminating. in the loweredge 4. Fixed adjacent the respective ends of support or guide 1, arethe downwardly extending brackets 5 and 6, the latter of which at itsinner end is formed-with'the opening 7, adapted to pivotally receive pin8, -carried .by the side an opening 12, which lies opposite the re--cess or notch formed by the cutaway por-- tion 10. The opposite sideportion 13 of the wringer frame carries an outstanding I pin 14, adaptedto pass through opening 12, which in conjunction with opening 7 and thewringer frame for a purpose herelna pin 8 pivotally mount the safetydevice uptzn r more fully set forth. Adjacent the end of permit removalof safety device A from t e wringer, which may be eflected by firstreleasing the same from pin 14 in a manner just described, and thenwithdrawing the same endwise from pin 8. v

To permit use of the safety device .on either side of the wringer, thecorresponding side portions of the opposite side are provided withsimilar pins to be received in openings 7 and 12in a manner which willbe readily understood from the above.

As noted in Fig. 1, the support; or guide 1 is formed at its oppositeends with the upstanding flanges 16, 17, which are inclined awayfrom-each other toward their outer edges, and which extend downwardly toedge 4. In addition, the guide 1 is provided with shoulders 17" whichlimit the inner movement or position of the lip 18 of the guide 1relatively to the bite of the rolls. When in fabric feeding position asshown in Figs. 1 and 2, the tip or inner edge 18 of the fabric guide 1will lie in the space hetween the peripheries of the rolls opposite the.bite thereof. and will be substantially touching more or less or justout of contact with the lower roll 19 on a line a slight d stanceoutwardly from the meeting llne or bite of the rolls.-

In the operation of my improved safety device, it will normally standaway from .therolls withthe lower edge of brackets 5 and 6 contactingface 21 of the drain board, or such other part of the wringer frame asmay be presented in the different makes of wringers. Assuming that thearticle to bewrung is of fair size, it will be thrown with its edgeslightly across edge 18 of support or guide 1, and support or guide 1will then be manually swung upwardly to bring it into the,position-shown in Fig. 2, at which time the adjacent edge of the garmentwill be picked up by the lower roll, and immedi-' ately carried betweentherolls, without the necessity of the operators' hand coming any closerto the rolls than lower edge 40f sup port orguide 1, which edge hemaygrasp in rotating the support or guide into operative position. It isofimportance to note that when theedge of the garment is thrown acrossedge 18, it will be passed between the rolls, with its edge underlapped,which I have found. prevents any possibility of the garment becomingwrapped around the wringer rolls. lnaddition, it must be evident thatreason of the fact that the attaehinent free to-he manually swung awayfrom nthe rolls it IS instantly releasable in and thus prevent the lipfrom being drawn into the bite of the rolls along with the fabric. Smallarticles, such as handkerchiefs, and the like, may be laid on to theupper surface of a larger article which is passing over the guidingmeans 1, and thus be carried between therolls, without the necessity,for example, of laying the article any closer to the rolls than uponcurved face 3, the articles being thus carried between the rolls uponthe larger article being wrung, thus again avoiding any possibility ofthe smaller articles becoming wrapped around the wringer rolls. Theouter portion 22 of the drain board on the opposite side of the machine,will serve as a guide toguide the wrung clothes into a basket,ifvdesired, without the necessity of the operator receiving the articlesin his hand from the outwardly moving side of the rolls. In passing overguiding means 1, buttons, and the like, will be caused to lie flat, andthus will go between edge 4, or grasp any other of the lower portions ofthe safety device desired, it will be readily seen that the fingers of.the operator may be kept well away from the wringer rolls, and anyliability of the fingers bemg caught therebetweenwill be entirelyeliminated'. While I have illustrated the spring arm 11 as one meansfor-removing the safety device from pins 8 and 14, I.wish it understoodthat other means may be used toiaccomplish this purpose, withoutdeparthig from the spirit of my invention. Due to the free pivotalmounting of th supporting or guiding means on the pins 1-4 and to thedisposition of the center of weight of the guiding means to the rear ofthe pin 14 and the location of the presenting edge. 18 adjacentthe biteof the wringer cylinders,

it is manifest that whenthe clothes and other fabrics are being pulledforwardly between the wringer rolls, as they drag over the supportingmeans, the dragging action 1 will maintain the latter inthe positionillustrated in Fig. 2, of the drawings, and that upon the completion ofthe feed of the fabric through the rolls, the safety device, willautomatically fall by gravity against drain I board 21 (or 22, dependingupon which side of the wringer the device is located) thus presentingedge 18 in an upward and well away from the wringer rol may then bepassed between the rolls by merely rotating table 1 to bring edge 18into position p s to receive a further article to be wrung, which thatdue to the curvilinear surface of the guiding means and the dispositionof its pivotal axis at 14, the upper edge 18 of the guiding means willmove in a substantially arcuzontal line of fabric feed into a position(when the lower end of the guide 3 contacts with drain board 21) suchthat the guiding means substantially shields or guards the openingbetween the rolls. 7 V j 1 Having now described my invention,

1. In a safety device'for wringer rolls, a for supporting articles to bewrung and hating arms at its respective ends, pivot pins on the wringerframe, said arms having openings near the free ends thereof for mountingon said pins to permit the guidingmeans to be swung toward or from thewringer rolls, and means adjacent the. opening in one of said arms topermit easy removal of the same that the safety device may be from itspin, so transferred to the other side of the wringer, when desired.

2. In a safety device for wringers, 'a movable guiding means forsupporting articles guiding means, said flanges to be wrung andcomprising a front edge adapted to receive the edge of an article to bewrung, said guiding means being movably mounted. on the wringer frame tobring said front edgeadjacent the line of contact of the two wringerrolls to cause feeding engageme ntof saidarticles bysaid rolls, and anupstanding flange on-each er 1'd of said being inclined outwardly awayfrom each other to guide said articles between the rolls. 7

3. In combination, a wringer frame com prising spaced side port-ions,and having a pair of rolls, a pin mounted in each of said side portionsand extending toward each I posltioned opposite the bite of the rolls,said other, a guiding means having a downwardly extending bracketadjacent each end, one of thereon,

said bracket, said guiding" and arranged to. have its upper. and lowerends move into substantial contact with the upper periphery of the lowerroll adjacent the bite between the upper and lower rolls and with thedrain 5. A manually operated fabric feeding at taehment for laundrywringer rolls, comprising in combination with a support on each side ofthe wringer frame, a fabric guide havinga quick detachable pivotalconnection whereby said guide can be readily mounted on either side ofthe rolls to be swung freely by hand from a position removed from saidrolls to a fabric feeding position opposite the bite of the rolls and tobe instantly releasable in said latter position to move away from saidrolls to relieve feeding of the fabric between the rolls, said guidehaving a forwardly extending fabric receivmg lip adapted to project intothe space between the opposed peripheries of the rolls opposite the biteof the rolls and substantially into contact with a roll peripherywhereby on rotation of the-rolls said fabric 15 grabbed by said ,rollsand fed therebetween, said guide having means for preventmg said lipfrom being drawn into the bite of the rolls along with said fabric.

6. The combination with wringer rolls, of a fabric receiving andsupporting member mounted contiguous to said rolls so as to be movabletoward and from the'rolls, said member having a free and unobstructedsurface on which thefabric is adapted to be p0- sitioned when saidmember is removedfrom the rolls and over which said fabric may be freelydrawn during fabric feeding, said member having a projecting lip overwhich the fabric maybe draped so that it will be movable with saidmember toward said rolls, and means for arresting movement of saidmember toward said rolls when said lip is the class described, the

said rolls, said guide providing a free and unobstructed surface onwhich said fabric is adapted to be draped when in position away from therolls and over which said fabric will be freely dragged when drawn bythe rolls, said guide having a forwardly projectin'g unobstructed lipover which said fabric is adapted to hang, which lip is adapted to bepositioned close to the bite of the rolls and substantially touch one ofsaid rolls, and means to positivelvlimit the inward movement of saidguide and thereby the inner- I most position of said lip to prevent saidlip from being drawn into the bite of the rolls together with the fabricduring its feeding movement.

8. The combination With Wringer rolls, of an arcuate fabric receivingand sup orting member pivotally mounted substantially at toward saidrolls'andmeans for arresting movement of said member toward said rollswhen said lip is positioned opposite to the bite of the rolls, saidmember constituting the sole means for bringing-the fabric-up to therolls and being movable towards said rolls by manual means alone, saidmember being so mounted as to automatically remove it from said rollsafter the fabric is disengaged therefrom.

In witness whereof, I hereunto subscribe my name to this s ecification.
